Outlook 365 extension endless login loop
We set up Hubspot CRM and Sales free version, with me as the super admin and my co-founder as another admin. I was able to install and log-in to the extension with no problem. However when my co-founder attempts to login, he is just redirected right back to the login screen with no error message. This same thing happens regardless of whether he tries to log-in through the Outlook desktop application, or through the Outlook 365 web app.
